Problem with Eclipse and GWT

[Christoph Breidert]

Hi everyone,

I had Eclipse 3.4 and GWT running perfectly under Ubuntu 9.04.

Since I updated Ubuntu to the latest version 9.10 I cannot start the
hosted mode browser any more. It just starts briefly and the closes
again. Also nothing responds onhttp:// localhost:8080. I tested this
with Eclipse 3.4 and 3.5 both give the same error.

The console log is this:

09.11.2009 20:30:44 com.google.apphosting.utils.jetty.JettyLogger info
INFO: jetty-6.1.x
09.11.2009 20:30:45 breidert.bse.server.EncodingFilter init

/usr/lib/jvm/java-6-openjdk/bin/java: symbol lookup error: /usr/lib/
xulrunner-1.9.1.4/libxul.so: undefined symbol:
PR_GetPhysicalMemorySize

The error tells me nothing, googling also does not bring anything that
makes sense to me. If anybody has an idea or hint it would be
appreciated, I have spent too much time and headbanging on this.

Cheers and thx, Christoph

actually the error tells all you need to know :)

undefined symbol: PR_GetPhysicalMemorySize

clearly the upgrade to 9.10 has replaced the /usr/lib/
xulrunner-1.9.1.4/libxul.so
library, and the new one does not export that method/function

I'm having a similar error (one library has been upgraded to
whatever.so.5 to .6 -- don't have it here, can't quite recall what it
was)

It all stems from the fact that hosted mode is using Jetty and SWT,
which (in my uninformed opinion) are old, brittle and unmaintained --
thank God Hosted Mode is going away in 2.0, in favor of OOPHM, or,
easier on the tongue... Dev Mode

I honestly don't really think there is a workaround (if anyone knows
of one, short of re-installing Ubuntu 9.04... which may actually be a
good idea anyway... 9.10 was a complete mess of a release if I've ever
seen one), so it's nailbiting time for 2.0 to become publicly
available and HM going aways for good....

Well, to be fair, 2,0ms2 is quite usable. I had tried 2.0trunk several months ago, and found the OOPHM wasn't ready; that's no longer the case.

Clearly, it's not available to you if you have some external constraints that prevent you from moving to a "development preview" release.

Installing 2.0 ms2 is as simple as downloading, copying to a separate directory, and pointing your environment to that directory. If it doesn't work, point back to 1.x

Thanks everyone for the replies. Great news group.

I fixed the problem by changing to Sun's JDK in eclipse's project
settings

Instead of /usr/lib/jvm/java-6-openjdk
I now use /usf/lib/jvm/java-6-sun-1.6.0.16

Now everything work's nice and smoothly just like before I upgraded
Ubuntu.

Cheers,

Christoph
